[0058] 显示模块18包括一个低功耗的多显示器54,例如专利US6249332和US6456348中所描述的英国马尔文ZBD显示器有限公司的双稳态LCD。 [0058] The display module 18 comprises a low-power multi-display 54, for example, a bistable LCD displays ZBD Malvern UK Patent US6249332 and US6456348 described Limited. 该显示器54能够以多种尺寸显示矩阵数列,特别是320 X 240,400 X 160或224 X 90像素,其中像素构成介于60与200dpi的图形图像。 The display 54 can display the number of columns in a matrix of various sizes, in particular 320 X 240,400 X 160 or 224 X 90 pixels, wherein the pixels constituting between 60 and graphic image of 200dpi. 通常,这意味着该显示器的尺寸在25至80毫米高,70至100毫米宽,能够显示IOOdpi的高分辨率图像。 Typically, this means that the size of the display in the 25 to 80 mm high, 70 to 100 mm wide, high-resolution image can be displayed in IOOdpi. 本发明的关键之处在于图像无需任何电力就能保持在显示器上, 其中电力只用于更新显示的图像。 The key point of the present invention is that an image can be maintained without any power on a display, wherein the power used only to update the displayed image. 因此,这种显示器中的电池寿命可长达数年。 Thus, such a display battery life of up to several years. 也可使用其他双稳态显示器,包括电泳显示墨、双稳态胆固醇、双稳态扭曲向列、铁电液晶和/或电铬显示器。 May also be used other bi-stable display comprises an electrophoretic ink display, a bistable cholesterol, bistable twisted nematic, ferroelectric liquid crystal and / or electrochromic displays. 所有这些显示器的共同点是适用于长期保持图像,无需任何供电;尽管有震动也可保持图像(例如,由于敲打或按压显示器带来的机械震动,或与环境突然改变相关的热击)。 All these displays have in common is suitable for long-term image, without any power; despite the shock can keep the image (for example, due to the knock, or press the display brought mechanical shock, or sudden changes in environment-related heat shock).

[0059] 显示器54与一个电子线路相连,包括一个微控制器52、存储器58、一个RF收发器56,例如半双工收发器、一个温度传感器66和一个电压转换模块68。 [0059] The display 54 is connected to an electronic circuit, comprising a microcontroller 52, a memory 58, an RF transceiver 56, such as a half-duplex transceiver, a temperature sensor 66 and a voltage conversion module 68. 显不模块18还包括一个电源供应器60,由两种不同显示模块18操作模式的电力形式。 No significant module 18 further includes a power supply 60, two different modes of operation the display module 18 in the form of electricity. 电源供应器60包括一个太阳能电池、电池或电池组62,例如锂-二氧化锰电池,以确保显示模块18的全面运作,例如确保与通讯模块16的铜须,保证低功耗(睡眠)的运作模式,以在RC振荡器64的帮助下实现模块同步化,在低耗能(例如,单纯展示)和高耗能操作模式之间切换。 The power supply 60 includes a solar cell, a battery or battery pack 62, such as a lithium - manganese dioxide battery, to ensure the full functioning of the display module 18, for example, the communication module 16 to ensure that the copper must ensure low power (sleep) of mode of operation, in order to implement the module with the help of synchronization RC oscillator 64, energy (e.g., the simple display) and the low power consumption operation mode is switched between a high energy. 在高耗能模式下,显示模块18通过RF收发器56接受命令和数据,执行命令要求,在完成指令后做出回应。 In the high energy consumption mode, the display module 1856 accepts commands and data via the RF transceiver, Run required to respond after the completion of the instruction.

[0061] 显示更新包括一个将图像下载到储存器58中的命令,随后是一个更新IXD显示器54的命令。 [0061] comprising a display update download images to the reservoir 58 command followed by a command 54 to update the display IXD. 显示更新要求不同的电压和时序,基于LCD显示器54的温度。 Display update requirements different voltages and timing, the LCD display 54 based on the temperature. 在显示器54更新期间,微控制器52获得来自温度传感器66的温度读数,通过电压转换模块68产生相应的显示更新电压,将预先确定的波形应用到IXD显示器54上,从而进行更新。 During update the display 54, the microcontroller 52 obtains a temperature reading from the temperature sensor 66, generates a corresponding display refresh voltage by the voltage conversion module 68, a predetermined waveform to be applied to the display 54 IXD, thereby performing the update. 在更新之前, 微控制器52关闭温度传感器66的电源。 Before the update, the microcontroller 52 a temperature sensor 66 off the power. 更新后,电压转换模块68断电,随后微控制器52 进入非常低功耗的待机状态。 After the update, the voltage conversion module 68 off, then the microcontroller 52 enters a standby state in a very low power consumption. 在待机模式下,微控制器52处于一个非常低功耗的状态,以节省电池电量。 In standby mode, the microcontroller 52 is a very low power state to conserve battery power. 在RF通讯期间,向微控制器52和RF收发器56供电。 During RF communications, the power supply to the microcontroller 52 and the RF transceiver 56. 在显示更新期间,向微控制器52、温度传感器66、电压转换模块68和显不器68供电。 During display updates, 52, temperature sensors 66, 68 and a voltage conversion module 68 without significant power to the microcontroller.

[0062] 通讯(RF)协议 [0062] Communications (RF) protocols

[0063] 参考图4是一个由通讯模块16向多个显示模块18传送信号70的示意图,其中信号70包括一系列不连续的时间分隔元件72 ;每个元件72包括一个同步或唤醒组件74, - 个数据或负载组件76,并与特定的时隙78相关。 [0063] Referring to FIG 4 is a schematic diagram of the communication module 16 to a plurality of display modules 18 transmits a signal 70, which signal 70 comprises a series of discrete time-division element 72; element 72 each comprise a wakeup or synchronization component 74, - data or load components 76 and 78 associated with a particular time slot. 这里使用了四个时隙78,每个时隙有一系列的标记信号元件72,方便与其组件显示模块18联系利用低电能和高频带宽度的同学协议。 As used herein, the four slots 78, each slot has a series of signal elements labeled 72, to facilitate their assembly module 18 contact the display protocol students using a low power and high frequency bandwidth degrees. 该通讯协议利用由通讯模块16发送的同步脉冲82的周期数列80,以使时间分隔的多路数据发送至目标显示模块18。 The communication protocol utilized by the cycle sync pulses 16 transmitted from the communication module 82 of the columns 80, so that the time-division multiplexed data is transmitted to the target display module 18.

[0064] 唤醒或同步组件74包括显示模块18和通讯模块16在时隙78中相互通讯的相关信息,以及精确测定显示模块18的唤醒时隙。 [0064] The wakeup or synchronization assembly 74 includes a display module 18 and communication module 16 communicate with each other information, and accurate determination of the slot 78 in the display module wakeup slots 18. 这正如图5所示那样,可以看出一系列80的同步数据包82可包括所有均匀分组的有关中心或基本数据包标签0的数据包82总和。 As shown in Figure 5, as it can be seen that a series of the isochronous packet shown in FIG. 80 about the center 82 may comprise the sum of all the packets uniform or substantially packet label data packet 0 82. 未来与显示模块18的相对时隙78同步化,显示模块18应进入高功耗模式,启动RF收发器56, 适当的接收基本的数据包标签0。 Future opposite slot 18 and the display module 78 of synchronization, the display module 18 should enter the high power mode start RF transceiver 56, the appropriate label receiving packets substantially 0. 如图5所示,收发器打开的时间比一个数据包略长(即大约4毫秒),相应地接收所有同步数据包82标签为-3 (即3个同步数据包82远离基本的同步数据包标签〇)。 As shown, the transceiver ON time is slightly longer than one packet (i.e., approximately 4 ms), thereby receiving all of the isochronous packet tag 5 82 -3 (i.e. 3 remote from the isochronous packet 82 substantially isochronous packet label billion). 因此,微控制器52能够校准显示模块18里的时钟,进而能够更精确地在合适的时间内在低功耗和高功耗操作之间进行转换。 Accordingly, the microcontroller 52 to calibrate the clock in the display module 18, and thus be able to convert between the right hours at low power and high power operation, more accurately. 因此,每个显示模块18中的时钟管理可以是相对较低的公差,其主要的时钟机制中包括位于通讯模块16内的晶体48,其具有较严的公差,容易受到自身低漂移的影响。 Thus, each display clock management module 18 may be a relatively low tolerances, which mainly includes a crystal clock mechanism located within the communication module 1648, which has a tighter tolerance, itself susceptible low drift. 在这种方式下,单个显示单元的成本可保持在最小水平,同时保证所耗电能尽可能保持在最低限度(因为同步化过程中出现的大量错误可能会来自使用低耐性时钟,可能会引起大量非必要的电能损耗)。 In this manner, the cost of a single display unit may be maintained at a minimum level, while ensuring that the power consumption can be kept as a minimum (since the number of errors that occur during synchronization may be come from the use of a low resistance clock may cause a large number of unnecessary power loss). 图5所示的显示模块18 的开关操作中可见第一漂移D补偿为-3到0,第二漂移补偿为+2到0。 The display module 5 shown in FIG. 18, the switching operation can be seen in the first drift compensation D -3 to 0, the second drift compensation of +2 to 0.

[0065] 在同步脉冲组件74之间的时期,显示模块18处于深度睡眠状态,或处于低能耗模式,掀起了低功耗RC振荡器64。 [0065] In the period between the sync pulse component 74, the display module 18 is in the deep sleep state, or in a low power mode, off a low power RC oscillator 64. 这一特性有助于延长电池寿命。 This feature helps extend battery life.

[0066] 数据包86的串联84在每个同步化脉冲组件74之后播放,具有每个信号元件72 的最大组合时间,或同步脉冲/数据包进发,不超过预定的时间,例如1秒。 [0066] The packet 8486 is connected in series after each play sync pulse component 74, having a maximum aggregate time of each signal element 72, or sync pulse / data packet burst, not more than a predetermined time, for example, one second. 此外,发前听(LBT)在时隙78(或信号元件72)之间生效,以减少图6所示的工作比限制的影响。 Further, before the hair listen (LBT) effect between slots 78 (or signaling element 72) to reduce the impact operation shown in FIG. 6 than of limitation. 数据包分组告知,以提高协议效率。 Packet to inform a packet, in order to improve the protocol efficiency. 所有的数据包有一个唯一ID,如果因干扰而不能通过的话则会反复。 All packets have a unique ID, if due to interference, then it will not pass repeatedly.

[0067] 显示模块18根据其位置位于不同的时隙78,允许延长查询时间。 [0067] The display module 18 is located in a different time slot 78 depending on its position, allows extended query time. 这是为了确保在商店货零售商店的显示器分布。 This is to ensure the distribution of goods in shops and retail store displays.

[0068] 在数据传输阶段,传输协议利用一个滑动窗口协议,使用选择性重复。 [0068] In the data transfer phase, a transmission protocol using a sliding window protocol using selective repeat. 发送者和接收者都保持一个可接受序列号的窗口,仅回应那些没有错误的数据包。 Both the sender and receiver maintain a window of acceptable sequence numbers, only those error-response packet. 在单个的时隙78期间,该协议允许与最大数量和两个显示模块18进行通讯。 During a single time slot 78, the communication protocol allows a maximum number of 18 and two display modules.

[0069] 与显示模块18的通讯以会话的形式完成。 [0069] communication with the display module 18 is completed as a conversation. 每个会话可以包含任何数量的命令及其关联的数据。 Each session data may contain any number of commands and their associated. 在相关时隙中,会话可横跨多个传输元件72。 In a related slot, the session may span a plurality of transmission elements 72. 典型的图像和数据更新命令可能需要2个到4个元件72来完成。 A typical image data and update command may take 2-4 member 72 is accomplished.

[0070] 通讯协议采用了一系列定期的同步脉冲,由通讯模块16传输至可行的时间分配多路技术,从而发送到目标显示器。 [0070] The protocol uses a series of periodic synchronization pulses, transmitted by communications module 16 to a feasible allocation of time multiplexing, to transmit to the target display.

[0071] 频率分配 [0071] The frequency allocation

[0072] 在欧洲,中心频率869. 85MHz用作初始控制通道。 [0072] In Europe, the center frequency is used as the initial control channel 869. 85MHz. 数据通道位于频率范围在868. 0-868. 6MHz 和868. 7-869. 2MHz。 Data channels are located in the frequency range 868. 0-868. 6MHz and 868. 7-869. 2MHz.

[0073] 在美国,中心频率927.5MHz用作初始控制通道。 [0073] In the United States, the center frequency of 927.5MHz used as the initial control channel. 数据通道位于频道范围为902-928MHZ。 Data channels are located in the range of 902-928 MHz channel.

[0074] 其他地区的适当频率可以分配给相应的法规规定。 [0074] Other suitable frequency region can be allocated to the respective regulations.

[0075] 显示时隙 [0075] slot display

[0076] 每个系列显示模块18根据显示模块的位置和其位置的LSB确定探寻时隙78。 [0076] Each module 18 determines the display range 78 according to the seek time slot LSB position of the display module and its position. 时隙的确切数量可在初始安装过程中由显示配置控制传输,默认设置可以是8时隙。 The exact number of time slots may be configured to control transmission by the display during the initial installation, the default setting may be 8 slots. 时隙数量最好是2的次方。 Number of slots is preferably a power of two. 时隙中的显示分组可遵守以下规则:时隙=显示地址&(n_l)(其中n 表示时隙数目)。 Packet slots may display the following rules: slot = display address & (n_l) (where n denotes the number of time slots). 图4中使用的是4个时隙。 Used in Figure 4 are four slots.

[0077] 标准轮询 [0077] The standard poll

[0078] 单个的显示模块18适合与具有一个匹配网络ID的通讯模块16关联。 [0078] The display module 18 is adapted to the individual associated with a matching network having communication module ID 16. 一旦该显示器与通讯模块16关联,它即会唤醒每个适当的轮询周期,并试图寻找一个同步数据包82。 Once the display 16 associated with the communication module, i.e., it will wake up each appropriate polling cycle, and try to find a synchronization packet 82. 如果没有找到同步数据包82的话,它将重新回到休眠状态,并将在下一个预定的时隙78中被唤醒。 If the isochronous packet 82 is not found, then it will return to the sleep state and the wake-up 78 at the next scheduled time slot. 该过程中具有可编程的次数,例如10,如果没有找到一个有效的同步数据包82的话,该显示模块18将试图重新同步化。 Programmable number of times the process has, for example, 10, if not find a valid sync packet 82, then the display module 18 will attempt to re-synchronize.

[0079] 同步脉冲组件74之间的时间最好大于I. 1秒+10毫秒(见图4)。 74 between the time [0079] synchronization pulse component is preferably greater than +10 seconds I. 1 millisecond (see FIG. 4). 在初始标签配置期间,此设置是可以被配置的。 During the initial label configuration, this setting can be configured. 在图5所示的同步脉冲期间,同步脉冲组件74实际上包含背对背的同步数据包82串联广播。 During synchronizing pulse shown in FIG. 5, the sync pulse component 74 actually includes a synchronous serial data packet 82 broadcast back to back. 该同步脉冲数据包82包含三个主要信息集,即: The sync pulse packet 82 contains three main sets of information, namely:

[0080] 测量同步脉冲时期中心时间的场地88,允许显示器弥补其自身的振荡器漂移, [0080] The space center sync pulse measurement period of time 88, allows the display to compensate for its own oscillator drift,

[0081] 最好只有两个地址的显示模块18清单90,其通讯模块16可在时隙期间通讯, [0081] The display module 18 is preferably only two address list 90, which may be the communication module 16 in communication during the time slot,

[0082] 一个"时隙ID"92,且由该同步脉冲组件74的时隙针对,这使显示模块18能够更快地进行重新同步化。 [0082] a "slot ID" 92, and the synchronizing pulse by the slot 74 for the assembly, which causes the display module 18 can be quickly re-synchronized.

[0083] 唤醒周期94的长短取决于数据包结构中的显示模块18唤醒。 Length [0083] 94 wake-up period is dependent on the display module 18 wake-up packet structure. 作为最大的显示模块18,保持两个数据包82的清醒,最小为1个数据包。 As the largest display module 18, awake two data packets 82, the minimum of one packet. 如果一个有效的或完整的数据包82 已被处理,那么RF收发器56则会立即断电保护,最好是所有电器组件都是必不可少的,从而使同步化转换到显示模块16,以在预定的时间接受来自通讯器12的数据。 If a valid or complete packet 82 has been processed, then the RF transceiver 56 will immediately power protection, preferably all electrical components are necessary, so that the synchronized transition to the display module 16 to receiving data from the communication unit 12 at a predetermined time.

[0084] 该系统10最好配置为具有操作LBT特征,以处理同一无线频道的RF干扰。 [0084] The system 10 is preferably configured to have an operating characteristic LBT to process RF interference in the same wireless channel. 如果该发射器(通讯模块16)检测到频道上的干扰,则不会在预定的时间内消失,通讯模块16 跳过该时隙。 If the transmitter (communications module 16) detects interference on the channel, it will not disappear within a predetermined period of time, the communication module 16 skips the slot. 这是为了确保其余的显示模块18能够与同步组件74保持同步。 This is to ensure that the remaining 74 display module 18 can be synchronized with the synchronization component.

[0085] LBT周期被定义为:tL = tF+tPS,其中tF的固定值为5ms,tPS以假随机的方式以0.5ms的差异在0-5ms间变化。 [0085] LBT period is defined as: tL = tF + tPS, tF wherein the fixed value is 5ms, tPS in a pseudorandom manner the 0-5ms differences vary between 0.5ms. 如果固定时期没有该频道的干扰,则设为0。 If the fixed period not interfere with the channel, set to 0. 这在图6中显/Jn 〇 This substantially square in FIG. 6 / Jn

[0086] 数据传输 [0086] Data transfer

[0087] 传输协议采用修订的滑动窗口协议,使用选择性重复。 [0087] The transport protocol is revised sliding window protocol using selective repeat. 根据标准的滑动窗口协议, 定向的数据传输使两个部件间的数据发射器从根本上限定窗口大小,以限定数据包的数量,所有的数据包传送到另一个接收部件。 The standard sliding window protocol, the data transmission so that the data transmitter orientation between the two parts defining the window size from the root to define the number of packets, all packets to another receiving means. 发射器并不进一步发送数据包,直到收到来自接收部件接收到第一个数据包的回应。 The transmitter does not transmit further data packets, until the receiving means receive a response from the received first packet. 根据接收部件回应的数据包数目,发射器将进一步发送数据包,总数将达到但不会超过发送到接收部件的限定的窗口大小,接收部件并不发出回应或接受。 The number of packets received response component, the transmitter further transmits the data packet, adds up to but not beyond the receiving member is sent to the defined window size, the receiving part does not issue a response or acceptance. 因此,随着接收部件回应一个个数据包,数据包窗口发送渐进的幻灯片。 Accordingly, as a response to a receiving member packet, the packet transmission window progressive slides. 然而, 这里的变化是描述发送方和接受方维持一个可接受的序列数目窗口。 However, changes described here is the sender and receiver maintain a window of acceptable sequence numbers. 设置了最大的窗口尺寸,并且每个数据包具有唯一的5比特(16独特的数据包)ID,以便接收方能够清楚地分辨出重复数据包和新发送的数据包。 The maximum window size is set, and each packet has a unique 5-bit (16 distinct packets) ID, order receiving side can clearly distinguish duplicate packets and packets of a new transmission. 只有八个未公开的数据包可在任何情况非常出色。 Only eight unpublished data packets can be very good in any situation. 传输窗口从最老的未公开数据包ID(例如,最杰出数据包)中扩展8个数据包。 Extended transmission window 8 packets from the oldest unpublished data packet ID (e.g., the most outstanding packets). 因此,接收方保持8个数据包的接收缓冲区。 Thus, the receiver holding the receiving buffer 8 data packets.

[0088] 该确认数据包由一个16比特长的位图组成,对于显示器接收缓冲区的位置。 [0088] The acknowledgment data packet consists of a 16 bit length bitmap composition ratio, to the display position of the receiving buffer. 一个" 1"意指一个数据包被成功加载到该位置,而"〇"则表示该时间段没有接收到数据。 A "1" means that one packet is successfully loaded into the location, and the "square" indicates that the time period fails to receive data.

[0089] 数据传输有一个预定义的数目,每个时隙78中有两个显示模块18。 [0089] Data transmission has a predefined number, each slot 78 has two display modules 18. 假设单个显示模块18地址匹配,将发生以下过程: Suppose a single display module 18 matches the address, the following process occurs:

[0090] 1)根据轮询日程78唤醒显示模块18,设置一个同步数据包82,找到一个地址匹配(在区域90)。 [0090] 1) according to the polling schedule wakeup module 78 display 18, 82 is provided a synchronous packet, to find an address match (at region 90).

[0091] 2)显示模块18处于休眠状态,直到同步数据包74期满,然后唤醒准备在负载组件76中处理数据。 [0091] 2) the display module 18 in the sleep state until the expiration of the isochronous packet 74, then the wakeup preparation 76 processing data in the load assembly.

[0092] 3)以达到设定数目的方式将数据传输至显示模块18,这里是8个数据包86。 [0092] 3) to reach a set number of ways to transmit data to the display module 18, where 86 is the 8 packets. 如果这是在一段时间内的第一个数据包,那么适当的指令比特将重设数据包数目。 If this is the first packet in a period of time, then the appropriate command bit resets the number of packet data. 每个数据包86最好包括以下信息:网络ID,软件地址,数据包ID,命令信息,负载。 Each packet 86 preferably includes the following information: Network ID, software address, packet ID, command information loaded.

[0093] 4)如果接收到8个数据包,或者显示模块18收到最后一个数据包,那么它将立刻传送一个ACK数据包。 [0093] 4) If the received 8 data packets, or the display module 18 receives the last packet, then it immediately transmits an ACK packet. 在该时隙78内的最后一个数据包具有一个命令比特设置说明了这一事实。 In the last packet in this slot has a 78-bit command set illustrates this fact. 如果显示模块18检测到超过3ms至5ms的清晰频道,还将发送一个ACK,这意味着发送方停止了传送。 If the module 18 detects more than 3ms to 5ms clear channel, the ACK will send a, which means that the sender stops transmitting display (当发送方达到其窗口最高极限时出现这种情况)。 (This occurs when the sender window reaches its maximum limit).

[0094] 5)回应数据包包括一列需要重新发送的数据包。 [0094] 5) includes an echo packet of data packets need to be resent. 这在数据包结构中详细介绍。 This packet structure is described in detail.

[0095] 6)通信模块16重复发送发送失败的数据包,用更多可发送的数据填补剩余的数据包时隙,直到达到其传送窗口的上限。 [0095] 6) The communication module 16 repeatedly transmits transmitted data packet, data can be transmitted more fill the remaining time slots of the data packet, until the transmit window has reached its limit.

[0096] 7)重复此过程,直到发送了所有数据(时间段比特设置结束),或超过时间时隙78 〇 [0096] 7) Repeat this process until all the data transmission (the end bit is set period), or more than 78 billion time slot

[0097] 8)如果在所有数据发送到通讯模块16之前就已超过了时间时隙,则将通知微控制器44去排列剩余的数据,在随后的时隙中发送。 [0097] 8) If prior to the communication module 16 transmits all the data had exceeded the time slot, it will notify the microcontroller 44 to the arrangement of the remaining data, transmitted in the subsequent time slot. 这将从回应的最后一个数据包ID重新开始。 This is the last packet ID will respond to the start again. 该通讯模块16跟随最后一个数据包ID给所有开放的通讯会话。 The communication module 16 following the last packet ID to open all communication sessions.

[0098] 通讯模块16位于数据传送交换开始处的"会话起始"比特(例如,一种所谓的发送数据包)。 [0098] Communication module 16 is located at the exchange of data transfer start "session start" bits (e.g., a so-called packet transmission). 这将在连接两端重置数据包ID。 This resets the packet ID in the ends of the connection.

[0099] 通讯模块16位于命令数据包的"会话末端"比特,当没有更多的数据被发送到当前数据会话的显示器中。 [0099] Communication module 16 is located in the command packet "session end" bit, when no more data is sent to the display data of the current session. 在这一点,通讯模块16保持数据通道向显示器开放,直到接收到具有"会话末端"比特设置的数据包。 At this point, the communication module 16 remains open to the display data channel until receiving a packet having a "session end" bit set. 该比特的发送也将导致数据包ID在联系的两端重设。 The transmitted bit packet ID will also result in both ends of the link reset.

[0100] 即使没有更多要发送至特定显示模块18的来自通讯模块16的数据,如果没有接收到返回的"会话末端"数据包,那么通讯模块16将在下一个时隙中唤醒显示模块18。 [0100] 16 even if no more data from the communication module 18 to be transmitted to a particular display module, if not received "end session" data packet returns, the communications module 16 in the next slot 18 in the wake of the display module. 这是为了处理仍然有效但超过时隙的返回数据。 This is to remain effective but more than time slots return data.

[0101] 来自显示器的返回数据包应在回应数据包期间进行传输。 [0101] return packet should be transmitted from the display during the response packet.

[0102] 数据包之间的死空间最好不超过4. 5ms。 [0102] dead space between packets is preferably not more than 4. 5ms. 这是为了确保在另一个通道上竞争的发射器无法启动数据传输。 This is to ensure competition in the other channel transmitter can not start the data transfer.

[0103] 如果通过应用程序,数据包不从显示器接收缓存中移除,那么显示器将会发送一个(NYET)回应数据包。 [0103] If through the application, the packet receiving buffer is not removed from the display, then the display will send a (NYET) response packet. 这将强制通讯模块16重试该数据包,直到显示器能够回应该数据。 This will force the retry communication module 16 of the data packet, until the display responds to the data is possible. 在传输器12标出一个错误之前,将有一个可编程的重试次数。 Before the transmitter 12 indicated an error, there will be a programmable number of retries. 该通讯模块16在完成每个数据包传输时会先去倾听。 The communications module 16 will go to listen at the completion of each packet transmission. 如果在进发结束的预定时期它没检测到运输工具,那么它将假设先前的数据包丢失,并重新传输有效载荷。 If the end of the predetermined period marching transport it is not detected, then it is assumed that the previous packet loss, and re-transmitting the payload. 这又会防止该渠道被占用,这是系统流程控制的一个重要组成部分。 This will prevent the channel is occupied, which is an important part of the process control system.

[0104] 在恶劣的通道条件下,该协议回落到每个数据包接收回应。 [0104] Under adverse channel conditions, down to the protocol of each received response data packet. 然而,如果通道质量较好,八个数据包82将会逐个进发。 However, if the channel quality is good, eight packets 82 will be marching one by one. 图7中所示的是优化低BER的通道吞吐量(误码率)。 Optimize channel throughput, low BER (Bit Error Rate) as shown in FIG. 7.

[0105] 显示模块接收缓冲区只拥有窗口大小的许多位点。 [0105] The display module receives the buffer window size has only a number of sites. 这降低了协议内存总开销。 This reduces the protocol overhead of memory.

[0106] 图7,8,9详细描述了不同BER数据传输时隙的起始。 [0106] FIGS. 7,8,9 BER described in detail with different initial data transmission slot. 在这种情况下,假设没有数据从显示器返回。 In this case, it is assumed that no data is returned from the display. 参照图7,8,9,显示出同步数据包82串联80形成来自通讯模块16的信号70同步组件74,以及作为显示模块18中RF收发器56状态示意图。 Referring to FIG. 8, 9, 82 show a synchronous serial data packet 80 is formed from the signal 70 of communication module 16 synchronization component 74, and a schematic view of a display module 56 in the state of the RF transceiver 18. 收发器状态96显示, 在传输器或元件72的负载阶段日期期间,当同步数据包的串联80的一个地址匹配时,模块18进入接收模式,并受到数据包86串联84中的8个数据包86的进发。 Transceiver state 96 displays, during the load phase date transmitter or element 72, when an address serial synchronization packets 80 matches the module 18 goes into receive mode, and by the data packet 86 series 84 8 packets 86 marching. 在显示模块内存, 例如缓存区中存储的内容载于98。 The memory in the display module, such as the content stored in the buffer 98 is contained in. 回应数据包100是对通讯模块16的回应。 100 response packet is a response to the communication module 16. 图7具有一个低比特错误率,该回应数据包100回应所有前面的8个数据包作为一个整体被接收。 7 having a low bit error rate, the response packet 100 to respond to all of the eight preceding packet is received as a whole. 尽管具有一个中等的比特错误率,回应数据包1〇〇需要损坏数据包的重复,例如数据包3,该数据包会被重新发送。 Although having a moderate bit error rate, in response to repeated, for example 3 data packet, the packet will be re-transmitted packet needs 1〇〇 corrupted packets. 在较高的比特错误率情况下,显示模块18适应回复已成功接收并存储在当地存储器或缓冲区的单独数据包,因此执行一个标准的幻灯协议。 At higher bit error rate, the display module 18 has been adapted to respond successfully received and stored in a separate data packet or the local memory buffer, and therefore the implementation of a standard protocol slide.

[0107] 为了提高数据通道的利用,通讯模块16能够列出两个显示器,用于在一个时隙内的数据传输。 [0107] In order to improve the utilization of the data channel, communication module 16 can display two lists for data transmission in one time slot. 图10显示了这一过程。 Figure 10 shows this process. 该显示器位于本列表的第二位,定期唤醒以检测数据包是否正发送至主要显示器。 The display list is located in this second position, it wakes up periodically to detect whether the packet is being sent to the primary display.

[0108] 当通讯模块16完成向主要显示模块18的数据包传送时,显示模块18对已接收到数据的回应即刻发送给本列表中的第二个显示模块18。 [0108] When the communication module 16 completes the packet transfer module 18 to the main display, the display module 18 have been received the data sent to the immediate response of this second list 18 display modules. 这阻止了另一个系统夺取该通道。 This prevents another system to capture the channel. 这些数据包86在进发之间的4. 75ms空隙中是反复的。 These packets 86 are repeated at 4. 75ms in the gap between the marching.

[0109] 在一个进发期间的某一点,第二个显示模块18被唤醒,见图10第102行,发送一个回应,然后起始一个标准的数据传输。 [0109] wakes up at some point, the second display module during a marching 18, Figure 10 on line 102, sends a response, and then starting a data transmission standard. 这等同于数据进发的末端,通过扫描数据包的控制比特或检测没有数据传输的短暂时期。 This is equivalent to the end of the data marching, by controlling the bit scan data packet or detects a brief period of no data transmission. 数据储存在图10中所示的局部缓冲区104。 Data stored in the local buffer 104 shown in FIG. 10.

[0110] 回复数据包 [0110] reply packet

[0111] 回复数据包106是"捎带"至回复回应的。 [0111] reply packet 106 is "piggybacked" response to the reply. 图11呈现出可变长度的数据包。 Figure 11 presents the variable-length packets. 在这种情况下,第一个三个数据字节是回应,随后的四个字节是有效负载。 In this case, the first three data bytes are to respond, followed by four bytes of the payload.

[0112] 如果数据列队于显示器传输缓冲区,这将在下一个回应数据包中发回。 [0112] If the data transmission queued in the display buffer, which will be the next response packet sent back. 然后,该数据包由通讯模块16回应。 Then, the response packet by the communication module 16. 对该回复路径没有滑动窗口协议。 The return path is not sliding window protocol. 在制定的数据包外将产生一个"BAD",并终止现存的通讯时段。 Outside the established packet data will generate a "BAD", and terminates the existing communication session.

[0113] 如果来自通讯模块16的回应没有发送到显示器,该数据则将在下一个显示器到通讯模块16的回应期间重新发送。 [0113] If the response from the communications module 16 is not transmitted to the display, then the next display data to the communication module 16 responded during retransmission.

[0114] 初始同步化和重新同步化过程 [0114] initial synchronization and re-synchronization process

[0115] 如果显示模块没有与通讯模块16同步,则需要与发送器(通讯模块16)的轮询间隙重新同步化。 [0115] If the module is not synchronized with the communication module 16, the gap need to display the polling transmitter (communications module 16) of the resynchronization. 重新同步的要求发生在以下四种途径之一:通讯模块16不再发送同步数据包,通讯模块16不再以相应频率发送同步数据包,显示模块18的轮询期间在容忍度之外(例如,超过同步脉冲74的时间,接收到一个有效的数据包82),和/或在初始设置之后,当显示模块18试图定位一个有效的通讯模块16。 Resynchronization request is generated in one of four ways: the communication module 16 is no longer transmitting sync packets, the communications module 16 is no longer sent to the respective frequency synchronization packets, the display module 18 polling period outside tolerance (e.g. over time synchronization pulse 74 received a valid packet 82), and / or after the initial setting, when the display module 18 attempts to locate a communication module 16 effectively.

[0116] 通讯模块16最初尝试扫描本列表中的第一频率。 [0116] communication module 16 tries to scan a first frequency of the first list. 该扫描包括唤醒、执行运输检测或在频率通道上进行CD扫描。 The scanning includes a wake, or performing detection CD transport frequency channel scans. 如果没有传输器,显示模块16将恢复到休眠状态,其时间长度短于同步数据包进发长度。 If there is no transmission, a display module 16 will return to the sleep state, the length of time which is shorter than the sync packet burst length data. 如果显示模块18检测到一个传输器信号,它将保持两个同步数据包82的唤醒状态,并试图处理数据。 If the module 18 detects a transmission signal, it will keep the awake state two isochronous packet 82 and attempts to process the data. Display 如果它不能在数据包期间确保唤醒,则会回复到休眠状态,其长度短于同步数据包的进发长度。 If it can not be ensured during the wake-up packet will return to the dormant state, which is shorter than the length of the synchronization packet marching.

[0117] 如果有效的同步数据包82被处理,那么显示模块18知道哪些时隙与同步数据包82相关,以及同步数据包进发的时间补偿。 [0117] If a valid sync packet 82 is processed, the display module 18 knows which time slot 82 associated with the isochronous packet, a data packet burst and a synchronization time compensation. 这使之保持休眠,直到下一个轮询期间,期间显示模块18进入正常的操作期间。 This makes it remains dormant until the next polling period, the display module 18 enters the normal operation during the period.

[0118] 如果显示模块18不能在可编程的完成周期数后将一个有效的同步数据包82定位在初始频率,即少于5且最好为2,尝试定位同步脉冲到可用频率,在初始设置期间进行程控。 [0118] If the display module 18 is not valid after a programmable number of cycles to complete an isochronous packet 82 positioned at the initial frequency, i.e. preferably less than 5 and 2, attempts to locate the sync pulse frequency to be used, provided the initial during programmed.

[0119] 以同样的方式执行在一个频率上的扫描。 [0119] scanning is performed at a frequency in the same manner. 然而,显不器在一个略长的时期内保持唤醒状态,在列表中的每个唤醒时间的所有频率上执行CD。 However, no significant keeps awake for a slightly longer period, CD be performed on all frequencies each wake-up time in the list.

[0120] 如果在延伸时期进入睡眠的时间点上,显示模块18不能与通讯模块16同步化,例如尝试再次定位通讯模块16之前的15秒。 [0120] If the period extends into the sleep time point, the display module 18 can not be synchronized with the communication module 16, for example, previous attempts communication module 16 positioning again for 15 seconds. 这延长了电池寿命,并提供已储存的元件事例。 This extends battery life, and provides examples of saved elements.

[0121] 成组访问 [0121] Access group

[0122] 成组访问有两个方面,第一是将显示器分配为一组,第二是将数据发送到那一组。 [0122] There are two aspects of the access group, the first display is assigned to a group, and the second is to send data to that group.

[0123] 分配显示器 [0123] assigned a display

[0124] 有两种方法可用于分配显示器到一个特定组: [0124] There are two methods available for allocation to display a specific group:

[0125] •单一配置(回应):通讯模块16正常唤醒显示模块18,但其中一个数据包具有一个命令比特设置,随后一个命令将指派该模块发送到一个组ID。 [0125] • a single configuration (responded): the communication module 16 displays a normal wake-up module 18, but a command packet having a bit is set, then a command is sent to the module will assign a group ID. 这些数据包作为每个正常的数据传输协议而回复。 Each data packet as normal data transmission protocol reply.

[0126] •分组配置(不回应):这允许通讯模块16在轮询分组中同时分配给一套显示模块18。 [0126] • grouping configuration (not responded): This allows the communications module 16 in the polling packet while assigning to a display module 18. 在发送SYNC数据包82和特殊命令之后,例如显示器位置1位于一个预先决定的形式,显示器位置2位于另一个预先决定的形式,该轮询分组的所有显示器将被唤醒并处理数据包。 After transmitting the SYNC packet 82 and a special command, such as the display position of the 1 in a predetermined form, the display 2 in another position a predetermined form, all of the polling packet monitor wakes up and process the packet. 通讯模块16随后发送显示模块预期的具有预定结构的数据包,从而使得显示模块分组通过单一的数据传输而分配接收,并且被该组中的所有显示模块处理。 Communication module 16 then sends the display module expected data packet having a predetermined structure, the display module so that the received packet is allocated a single data transmission, and is processed all the display modules in the group.

[0127] 向一个分组发送数据 [0127] transmits data to a packet

[0128] 当通讯模块16能够与显示分组通讯时,它传送一系列特定的同步数据包。 [0128] When the communication module 16 capable of packet communication is displayed, it transmits a specific set of synchronization packets. 这些具有位置1场地以一种预期的方式设置,位置2场地被设置为可与通讯模块16通讯的分组。 These positions have a site in a desired manner, the position of the site is set to be 2 packet communication with the communication module 16. 此时,数据流向相关分组中的所有显示器,即使没有ACK数据包回应。 In this case, all the display-related data flow packets, even if there is no ACK packet response. 传送的数据包ID最好随每个传输数据包增加,取决于显示模块18确定是否收到正确的数据。 Preferably ID packet transmitted with each data packet transmission increases, depending on the display module 18 determines whether it has received the correct data.

[0129] 如果显示器位置1设置为OxFFF,显示器位置2设置为0x0001,那么下一个数据包将预定仅在组1中标记。 [0129] If the display position is set to 1 OxFFF, the display position is set to 2 0x0001, then the next data packet to a predetermined flag in the group 1 only. 重要的是它与时隙分组(在显示器位置的LSB基础上)不同。 It is important that the packet time slots (on the basis of a display position on the LSB) are different. 有必要在不同时隙重复几次该过程,以确保所有的显示器完成更新。 Necessary to repeat the process several times in different time slots to ensure that all of the display update. 一个分组位置,例如OxOOOO能够保留,并用作所有显示器的播放位置。 A packet location, e.g. OxOOOO can be reserved and used as a playback position of all displays.

[0130] SYNC数据包最好产生于先前描述相似的数据结构,包括数据包长度的确定信息, SYNC数据包进发中的同步数据包数目和/或剩余的SYNC数据包数目,以及应对的相关显示分组信息应完全贯穿第一显示位置和第二显示位置。 [0130] SYNC is generated in the data packet is preferably the previously described similar data structures, including packet length determining information, the number of synchronization data SYNC packet data packet burst and / or the number of packets remaining SYNC, and display related response information packet should extend completely through the first display position and the second display position. 信息最好根据时间时隙提供,确认瞄准SYNC进发。 The time slot information is preferably provided, aiming SYNC confirmation moving. 数据包最好在基本位置和显示器之间进行传输,包括相应的位置信息和在一个特定数据包进发中的相关数据包的序列信息。 Preferably data packets transferred between the basic position and the display, including the sequence information of the corresponding location information and associated data packet in a data packet burst in particular. 例如,一个数据包可能包括480比特,包括一个命令元件,一个"数据包剩余"元件和实际数据(例如以472比特的顺序)。 For example, a data packet may comprise 480 bits, including a command element, a "remaining packets" and the actual element data (e.g. in the order of 472 bits). 该命令字节可能包括一个命令比特、起始时期、起始时间时隙、结束时期和一个数据包ID。 The command byte may include a command bit, start time, starting time slot, and the end of a period of a packet ID. 一个数据包最好由显示器产生,回复到基础位置,包括位置、时隙等相关信息,以及一个本身含有一个命令字节和/或回应数据的数据包。 Preferably a data packet generated by the display and returns to the base position, including position, time slot and other related information, and a command byte itself comprising a and / or response data packet. 特别的是,该显示器适应于成功回应接收到的数据, 并以前面所述的方式进一步要求可能已乱码的数据。 In particular, the display is adapted to respond to the success of data received, and in the manner described above may have further requirements of garbled data.

[0131] 在不可恢复连接错误事件发生时,显示器18超时并进入睡眠,其中信息回馈到通讯模块16。 [0131] When connected to an unrecoverable error event occurs, the display 18 times out and goes to sleep, in which the information back to the communication module 16.

[0132] 显示器重新编程 [0132] Display reprogramming

[0133] 至少每15s,在方便的时刻,显示器设置一个预定的地址,例如其H/W位置,一个预定值,例如0x00,并利用一种预定的协议扫描该控制频率。 [0133] Each of the at least 15s, at a convenient time, a predetermined display is provided to address such that H / W position, a predetermined value, for example, 0x00, and utilizes a predetermined protocol controls the scanning frequency. 这可能发生在同步脉冲组件74 之间,而显示器不与通讯模块16通讯。 This may occur between the sync pulse component 74, and the display 16 does not communicate with the communication module. 这可使显示器很容易的重新编程。 This allows the monitor to be easily reprogrammed.

[0134] 多重通讯模块16 [0134] multiple communication module 16

[0135] 多重通讯模块16能够通过在商店分派额外的发射器处理该系统10到不同的频率。 [0135] multiplex communications module 1610 to a different frequency by the dispatch system to handle the additional transmitter in the store.

[0136] 显示器与任何有效的通讯模块16相关,该通讯模块能够在任何频率上找到匹配的网络ID,在初始的配置步骤期间进行下载。 [0136] a display associated with any active communication module 16, the communication module ID to find the matching network at any frequency, download configuration during the initial step.

[0137] 这取决于PC应用软件反过来利用不同的通讯模块16试图与显示器通讯。 [0137] This in turn depends on the PC application using different communication module 16 attempts to communicate with the display. 一旦显示器成功通过一个通讯模块16发送数据,它将作为该设备的首要发射器。 Once the display 16 transmits data via a communication module successfully, the device will serve as the primary transmitter.

[0143] 应用程序界面(API)包括提供第三方应用与通讯系统之间的主要界面。 [0143] Application Program Interface (API), including providing primary interface between third-party applications and communication systems. 在该API 中提供有一个全面的命令库,以使第三方应用可行,例如图像渲染模块28联合图像到产品上,并推进显示模块18上的图像更新。 In this API provides a comprehensive library of commands, so that a viable third-party applications, such as image rendering module 28 to the Joint Photographic products, and promote the updated image on the display module 18. API还提供了管理产品创造和删除功能,显示模块18与产品联合,补偿状态和统计信息。 API also provides management products to create and delete functions, the display module 18 product information and joint compensation status and statistics.

[0144] 在系统10安装期间,API用于在数据库20中创造产品和显示模块。 [0144] During installation of the system 10, API is used to create products and display module 20 in the database. 在创造后,API 常用于将显示模块18(或多重显示模块)与产品结合。 After creation, API used in the display module 18 (or multiple display module) binding the product. 一旦该联系建立起来,API可保证随时的产品更新要求,适当的显示模块与产品连系,发送图像更新。 Once the link is established, API ensures product updates at any time request the appropriate display module product line, send the image update.

[0145] 在系统10安装后,当图像渲染模块28有产品的新图像时,API被访问。 [0145] After the system 10 is installed, the image rendering module 28 when a new image of the product, the API was accessed. 在图像更新收到时,在将显示模块更新至通讯器服务队列之前,需要API验证图像的大小和格式,以实现向与产品相关的显示模块18传输。 When an image update is received, the display will be updated prior to the communication service module queue, API authentication required image size and format to achieve transmission to the display module 18 associated with the product. API等待来自通讯器服务的回应,并将之返回至访问应用。 API waits for a response from the communication service, and return it to access the application. 如果检测到失败,API也可进行更新重试。 If a failure is detected, API may be updated retry.

[0146] 图解用户界面(⑶I) [0146] Graphical User Interface (⑶I)

[0147] ⑶I包括一个软件应用,它可以为用户提供一个安装和配置API与数据库20的途径。 [0147] ⑶I comprises a software application, it can provide users with a way to install and configure the database 20 API.

[0148] Gn提供了一个创建和删除产品与显示模块的途径,联合显示模块与产品,用于以图解的形式显示使用统计和审计信息。 [0148] Gn provide a way to create and delete products and display modules, display modules and joint product for use in the form of graphic display statistics and audit information.

[0149] 产品规则引擎26 [0149] product rules engine 26

[0150] 产品规则引擎26包括一个软件应用,其能够控制产品更新,呈现出一个用户界面,以显示更新统计和状态信息。 [0150] product rules engine 26 includes a software application that can control product updates, showing a user interface to display statistics and update status information.

[0151] 当系统规则引擎34确定了产品需要的新图像时,它将安排产品规则引擎26的运行。 [0151] When the system rules engine 34 to determine the new image of the product needs, it will arrange the product rules engine 26 runs. 产品规则引擎26从系统规则引擎数据库38中收回产品数据,并安排图像渲染器28产生一个产品的新图像。 Product rules engine 26 to recover the data from the product database system rules engine 38 and arrange image renderer 28 produces a new image of a product. 这在图14中的步骤120至124中表示出来。 This step is represented in FIG. 14 to 120 124.

[0152] -旦图像提供了一个产品更新命令,包括通过API向显示器网络管理模块22提供新的图像。 [0152] - Once the image update command provides a product, including new image to the display network management module 22 through the API. 随后,该图像被传送至适当的显示模块18,并在步骤132显示。 Then, the image is transferred to the appropriate display module 18, and displayed in step 132. 另外,通讯器12 从显示单元18重新回到更新状态,如步骤134,并且显示器网络管理模块22监测更新队列, 并在数据库中的审计表格中储存状态,如步骤136。 Further, the communicator 12 back to the display unit 18 from the update status, in step 134, and the display network management module 22 monitors the update queue, and the status of audit table stored in the database, as in step 136. 重复该循环以维持完整的数据库审计表格,并且该产品规则引擎138通过API定期地回复状态,直到该过程完成,见图14中的步骤140。 This cycle is repeated to maintain the integrity of the audit database tables, and the product rules engine 138 through the API recovered state periodically, until completion of the process, see Step 14140.

[0153] 根据图15,如果一个分组产品更新需求如步骤142所要求的,那将有一个组更新过程,在那里确定商业规则引擎34。 [0153] According to FIG. 15, if a packet needs to update the product as required in step 142, that there will be a group update process, where the business rules engine 34 is determined. 例如,一组显示模块18可能会根据邻近和/或产品类型进行分组,需要一个分组更新,从而改变显示图像(见后面的讨论)。 For example, a display module 18 may be set according to adjacent and / or product type packet, a packet needs to update to change the display image (see discussion below). 在步骤144,产品规则引擎要求提供产品图像,并且图像渲染器28提供步骤146的图像。 In step 144, the product rules engine request product images, and the image renderer 28 providing an image of step 146. 产品规则引擎26向显示网络管理模块22发送"开始/结束分组"命令,对于每个产品,产品规则引擎26向显示器网络管理模块22发送一个下载图像命令。 Product rules engine 26 to the display network management module 22 transmits the "Start / End packet" command, for each product, product rules engine 26 sends a download network management module 22 to the display image command. 产品规则引擎26进一步项显示器网络管理发送一个末端分组命令,D匪22创立分组,并列出通讯器12的下载图像命令,在步骤154所示的分组中,使显示器18与产品联系。 Product rules engine 26 further entry display terminal to send a network management command packet, D 22 bandit creation packet, and download the image communications command lists 12, as shown in the packet in step 154, causes the display 18 to contact with the product. 该通讯器12向各组指派显示器,并为之下载图像, DW22监视图15中的步骤158所示的更新队列。 The communication unit 12 is assigned to each group of monitors for, and download the images, as shown in step 158 in FIG. 15 DW22 monitoring update the queue.

[0180] •根据存货水平和存货水平变化率,自动更新价格信息。 [0180] • inventory levels and inventory levels based on the rate of change is automatically updated price information.

[0181] 参见图19,显示了如何利用发明控制系统维持商业规则。 [0181] Referring to Figure 19, it shows how the control system of the invention to maintain the business rules. 这里的系统规则引擎(SRE34)监测数据库38,包括步骤226所示的产品价格和储存信息。 Here the system rules engine (SRE34) monitoring database 38, including price and product information stored in step 226 shown in FIG.

[0182] SRE34查询步骤268中的存货变化,在无变化时继续监测数据库38,通过询问过程形成回路。 The inventory changes 268 [0182] SRE34 inquiry step to continue monitoring database 38 when no change in the loop formed by the interrogation process. 然而,在库存变化时,系统规则引擎34如272所示设置一个交叉电池领域为零。 However, changes in the inventory, the system rules engine 34 is provided as shown in a cross-cell field 272 is zero. 在询问步骤274,如果库存大于或与预定的高限制相等时,设置库存为步骤276所示的"有现货",图像渲染器28能够在产品和价格的基础上创造一个图像,数据库信息储备和交叉电池从适当的惯例数据库38抽取数据,从而产生图19中图像I中所示的图像。 In inquiry step 274, if the stock is greater than or equal to a predetermined high limit set for the inventory "stock" as shown in step 276, the image renderer 28 to create an image on the basis of products and prices, and database information storage cROSS cell extract data from database 38 the appropriate routine, thereby generating an image shown in FIG. 19 in image I. 产品规则引擎26进入产品更新,确保新图像呈现在相应的显示模块18上。 Product rules engine 26 into product updates to ensure that the new image is presented on the appropriate display module 18.

[0183] 当库存高于或等于询问阶段286上预设的"中等"存货水平时,库存则设置为"有限的"库存,如步骤288,并且步骤278中的过程将在随后进行描述。 [0183] When the stock than or equal to the predetermined interrogation stage 286 "medium" stock level, inventories set to "limited" inventory, step 288, and step 278 will be described in a subsequent process.

[0184] 如果存货不认为是高水平或中等水平时,在询问步骤219,商业规则引擎SRE34查询库存是否大于〇,如果大于〇,那么库存则设置2 "低水平库存",使用图像渲染器28和产品规则引擎26创造适当的图像。 [0184] If the stock is not considered to be high or medium level, in inquiry step 219, the business rules engine SRE34 check stock is greater than the square, if more than billion, the stock is set 2 "low inventory", using the image renderer 28 and product rules engine to create the right image 26.

[0185] 然而,如果确定步骤290时有0个库存,那么库存设置为"无存货",交叉电池配置为步骤278所示的相关产品的适当图像。 [0185] However, if step 290 determines when 0 inventory, the inventory is set to "no inventory" cross-cell configuration suitable image related to the product shown in step 278.

[0186] 显示模块18定时更新 [0186] The display module 18 updates the timing

[0187] 显示模块18定时更新提供了一个实现分组更新的可选方法。 [0187] The display module 18 updates the timing provides an alternative method of implementing the packet update. 利用这种方法,显示模块将在某一时刻显示出图像更新,独立于通讯器12和显示网络模块。 With this method, the display will show the image update module at a time, independently of the communications network 12 and a display module. 这排除了分组更新广播的需要。 This eliminates the need to update the broadcast packet. 如图18所示。 18.

[0188] 多显示模块 [0188] the multi display module

[0189] 根据图20,其中显示了一个单独的显示通讯模块57和多显示器54i,54i i,54i ii, 54iv的结合,它们共同组成了一个架子边缘系统:提供了一种更新沿架子边缘上的多个显示器的简单有效的方式,通过共享单一的通讯模块降低架子边缘整个系统的成本。 [0189] According to FIG. 20, which shows a multi-monitor display separate 54i, 54i i, 54i ii, combined communications module 57 and 54iv, which together form a shelf edge of the system: a method of updating the provided along the edge of the shelf simple and efficient manner a plurality of displays, the cost by sharing a single edge of the shelf module reduces the overall communication system.

[0190] 显示通讯模块57 [0190] shows the communication module 57

[0191] 显不通讯模块57包括一个微控制器52',一个RF收发器56',一系列信心通路界面58和一个电力供应60'。 [0191] does not substantially comprise a communication module 57 microcontroller 52 ', an RF transceiver 56', via an interface 58 and a series of confidence a power supply 60 '. 多个显器54共享一个单一的显通讯模块57,向更新每个显示器54提供所需数据。 A plurality of substantially 54 substantially share a single communication module 57, to provide the necessary data to the display 54 to update each.

[0200] 电力计算 [0200] Power Calculation

[0201] 利用一个或多个系统特征,以及上述方法中的一步或多步,实现低电力损耗,提供了随后的电力消耗数据。 [0201] using one or more system features, as well as the above method one or more steps, to achieve low power consumption, and then provides the power consumption data. 在这一点,一个单一的电池承担供应1.53Ah的能量(例如,大约电池组总电量的90%)。 Energy supply 1.53Ah assume at this point, a single cell (e.g., about 90% of the total charge of the battery pack). 电池的放电将依赖于温度。 Discharge of the battery will depend on the temperature. 假定恒量23degC。 Assumed constant 23degC.

[0202] 每个显示模块18的电力使用包括表1中所示的下列典型组成: [0202] Each of the display module 18 comprises a power usage shown in Table 1 in the following typical composition:

Figure CN102165411BD00221

[0205] 上面计算了一个4" QVGA显示单元需要5. 7mJ进行更新,同时需要额外的18. 3mJ 用于DC到DC转换器,提供驱动该显示器的电压。行电压为30V,柱压为5V,DC-DC转换器功率假定为这些计算的85%。显示单元的有效负载为33kQ。1-bit显示的图像更新时间是最差情况使用时间(每个图像1. 578秒),RF接收时间为6. 373秒。 [0205] The above calculation of a 4 "QVGA display unit 5. 7mJ need to be updated, while the need for an additional 18. 3mJ DC to DC converter, a voltage for driving the display. Row voltage is 30V, 5V pressure column , DC-DC power converter is assumed to be 85% of the calculated display unit is a payload 33kQ.1-bit image update time displayed is the worst case time (1.578 seconds per image), RF reception time to 6.373 seconds.

[0206] 图22是一个显示利用本发明系统的电池寿命(数年中)理论计算图解,其中每天图像更新几次(1到50次)。 [0206] FIG. 22 is a display system using the present invention, battery life (in years) illustrates a theoretical calculation, wherein the image update several times a day (1 to 50).

[0207] 清楚地看到,驱动显示器是耗电的主要方面:每天只不过更新图像50次。 [0207] clearly seen, the driving power of the main aspects of the display: the image is only updated 50 times per day. 这表明使用双稳态显示器的重要性。 This demonstrates the importance of bi-stable display use. 如果显示模块需要恒定的电力,那么即使是最低功耗的单稳态类型或目前可用的放射型显示器,其电池寿命最多也就是数天。 If the display module requires a constant power, even if it is the lowest power of monostable type currently available or emission displays, battery life that is up to several days.

[0208] 典型零售应用中,显示器每天最多更新2到5次。 [0208] In a typical retail application, updating the display up to 2-5 times per day. 对于每天更新5次来说,电池的理论寿命大约为9年,如果轮询时间约为20秒。 For updated five times per day for the theoretical lifetime of the battery is about 9 years, if the polling time is about 20 seconds. 减少轮询时间8秒,降低5%的电池寿命, 大约为8. 5年。 Reducing polling 8 seconds, a 5% decrease battery life of about 8.5 years. 提高轮询时间的规律性到每2秒一次,将对电池寿命有显著作用,减少40% 的使用寿命。 Polling time to improve the regularity of once every 2 seconds, the battery life would have a significant effect, a 40% reduction of the service life. 这在图23中描述。 This is illustrated in FIG. 23.

[0209] 实际的电池寿命将不会达到理论值,因为电池的保质期是有限的。 [0209] The actual battery life will not reach the theoretical value, since the shelf life of the battery is limited. 例如,用于计算的典型电池有7年的保质期。 For example, a typical battery is used to calculate the seven-year shelf life. 因此,没有优化轮询时期以延长电池寿命的方法。 Thus, no polling period to prolong battery life optimization method. 对于每天平均更新6次图像来说,轮询时间最好在4至8秒之间,最好是8秒。 Average image is updated six times per day, preferably in the polling time between 4-8 seconds, preferably 8 seconds.

[0210] 在零售应用中,存在单个通讯设备更新的元件数目与轮询时间之间的权衡。 [0210] In retail applications, there is a tradeoff between the number of individual communications device updates the polling time element. 如果零售商要求改变1000个标签,那么这将在一晚上完成。 If the retailer is required to change the 1000 labels, then this will be completed in one night. 通常,零售商可能需要在长达8小时的期间更新所有标签。 In general, retailers may need to update all tags during up to 8 hours. 更新所有标签所需的时间将在轮询时间指令。 Update instructions required for all tags in the polling time. 如果是8秒,那么1000个标签将在2. 2个小时内完成连续的更新,这是非常令人满意的,同时确保电力使用最小化。 If 8 seconds, then the 1000 label is completed within 2.2 hours of continuous updating, which is very satisfactory, while ensuring that the power usage is minimized.

[0211] 其他应用可能具有不同的使用率。 [0211] Other applications may have different usage. 例如,如果应用包括选择显示器将预存的图像加载到闪存,这些图像之间有一个由观看者转换的界面,那么显示器每天可更新50到100 次。 For example, if the application comprises selecting the display of the stored image into the flash memory, converted by a viewer interface between these images, the display can be updated 50 to 100 per day. 在这种情况下,保持更长的轮询时间没有优势(由于轮询时间的电力是独立的--见图22)。 In this case, the holding time is not longer advantage polling (polling time since the power is independently - see FIG. 22). 该应用的关键在于最小化更新图像所需的电力和/或最大化来自电池的能量供应。 The key to this application is to minimize the power required to update the image and / or maximize the energy supply from the battery. 例如,减少更新显示器所需的时间,显示器装载量(电容和轨道电阻),以及使用的电压都是降低显示能耗的有效手段。 For example, to reduce the time required to update the display, the display load rate (track resistance and capacitance), and the voltage used is an effective means of displaying the energy consumption is reduced.

[0212] 已经计算了小型显示器需的最佳SYNC或轮询时间。 [0212] small display have been calculated for an optimal SYNC or polling time. 假设Vied = 15V,Vd = 3V, 有效负载仅为15k Q,即一个2"寸的120X 160显示设备。该显示更新时间为0.6秒,RF接收时间为图像内容的1/4,为1. 59秒。随着本发明中的RF系统的应用,我们能够获得图24 中所示的电池寿命与轮询时间的关系。 Suppose Vied = 15V, Vd = 3V, payload only 15k Q, i.e., a 2 "120X 160-inch display device. The display update time is 0.6 seconds, the RF reception time of 1/4 of the image content, is 1.59 sec. with the application of the RF system of the present invention, the relationship between battery life and we are able to polling time is obtained as shown in FIG. 24.

[0213] 显而易见的是,由于在写入时期,显示器和RF的负载量较小,该规格的(1.7Ah)电池将可使用相当长的时间。 [0213] will be apparent that, since the write period, smaller displays and RF loading, the specification (1.7Ah) battery will be used for a long time. 轮询时间将可设置为2秒,电池寿命为5到7年,且每天更新5 次。 The polling period may be set to 2 seconds, the battery life of 5-7 years, and updated five times a day. 另一种方案是相同的显示器每天可平均更新15次(SYNC时期为8秒),同时保持5至7年的电池寿命。 Another solution is the same display can be updated 15 times per day on average (SYNC period is 8 seconds), while maintaining 5 to 7 year battery life.

[0214] 另一种重要的设计考虑可考虑到小型显示设备中:也就是成本和大小。 [0214] Another important design consideration may take into account the small display device: i.e. cost and size. 通常都考虑减少的方法。 Usually consider reducing method. 例如,3个扣式电池可向4"QVGA提供I. 7Ah的电力,而仅用2个电池就可供2"小型显示器。 For example, three button cell may "provide power I. 7Ah the QVGA, and only for two batteries 2" to 4 small display. 因此,小型显示器的能力供应总量大约为l.OAh。 Therefore, the total supply capacity of a small display about l.OAh. 也就是说图24的分析趋向于图23的分析。 That analysis Trend Analysis 24 Figure 23 in. 在这种情况下,最佳的SYNC时期(轮询时间)也是介于4至16秒之间,最好接近于8秒。 In this case, SYNC optimum period of time (polling time) is between 4-16 seconds, preferably close to 8 seconds.

[0215] 总之,最佳的轮询时间(SYNC时期)与显示器的大小和图像、平均更新的次数和电池的总电量供应(即保质期、温度作用和电流排出)有关。 [0215] In summary, the best time polling (SYNC period) and the size of the display image, the total power supply battery and the average number of updates (i.e. shelf-life, the effect of temperature and current discharge) related. 最佳轮询时间介于2至16秒: 低于2秒,RF SYNC需要更多的电力,限制显示器到最佳的最低能耗;高于16秒,更新大量显示器的时间超过最小的额外收益(因为电池的保质期和相对高的重要性与显示器的更新有关)。 Best polling time is between 2-16 seconds: less than 2 seconds, RF SYNC more power is needed to limit the display to the optimal minimum energy; than 16 seconds, the display update time exceeds a minimum lot of additional revenue (because of relatively high importance and the shelf life of the battery and display related updates). 实际应用中,8秒被认为是最合适的。 Practical applications, eight seconds is considered to be the most appropriate.

[0216] 分组更新 [0216] Update packet

[0217] 该系统的一个方面是利用分组更新来同时或并联地更新一些或所有的组件。 One aspect [0217] of the system is to use packet update or parallel update simultaneously some or all of the components. 在一天的过程中,通过使用预存的图像完成加载到每个组件(显示模块18),并储存在闪存中, 且直到该组件收到分组更新要求才会显示。 In the course of the day, through the use of pre-stored images loaded into each completion assembly (display module 18), and stored in the flash memory, and the assembly until the update request packet is received it will be displayed.

[0218] 分组更新过程可见于图25中的流程图。 [0218] packet update procedure may be found in the flowchart in FIG. 25. 实际操作中,一些标签不会在第一次尝试中成功更新,因为他们受到来自环境的影响,或比大多数标签位于与传输器更远的距离。 In practice, some labels will not successfully updated at the first attempt, because they are affected from the environment, or than most labels and transmitter located farther away. 为了最大化更新的表情数量,分组更新命令重复三次,以减少损失。 In order to maximize the number of updates of expression, a group update command is repeated three times to reduce losses.

[0219] 实际操作中,在典型的超市中,该系统标签成功率为97%,距离传输器IOOm远。 [0219] In practice, in a typical supermarket, the label system success rate of 97%, far from the transmitter IOOm. 如果随机事件引起3%的损失(例如,来自顾客的干扰),那么重复的分组更新将可确保100(1-0. 033) %的标签不能正确更新:即在100000个显示器中有3个。 If the random event causes loss of 3% (e.g., from the customer's interference), then the duplicate packets 100 will ensure that the update (1-0033.)% Of the label are not updated correctly: i.e., there are three displays at 100,000.

[0220] 实际操作中,这种损失不是随机的,它更可能发生于某些标签。 [0220] In practice, this loss is not random, it is more likely to occur in some labels. 在这种情况下,第二次和第三次分组更新的成功啦将会降低。 In this case, the second and third groups successfully updated it will be reduced. 在这种情况下,显示器将会以传统的方式,随着分组更新进行逐个更新。 In this case, the display will in a conventional manner, as by-update update packet. 但这需要一些时间。 But it will take some time. 本发明的另一方面是减少了分组更新后的选择连续更新序列的时间,那些组件最常发生更新困难,因此最可能在分组更新序列中失败。 Another aspect of the present invention is to reduce the time of selecting the packet sequence updated continuously updated, difficult to update those components most often occurs, therefore most likely to fail in the update packet sequence. 控制通讯系统的软件将获得哪些标签最易更新失败的信息,例如,每个组件的局部环境或距离传输器某组件的距离。 Tag information which is most likely to fail to update e.g., a component of the distance from the transmitter or the local environment of each component of the control software of the communication system will be obtained.

[0256] 在另一个实施例中,显不系统10还包括一系列RF收发器56和标签306 (图26), 还有库存的RFID标签。 [0256] In embodiments, the system 10 is not significant in another embodiment further includes a series of RF transceiver 56 and the tag 306 (FIG. 26), as well as the RFID tag stock. 每个显示元件18有一个RF收发器56,它能够进一步促进检测预定范围内的所有RFID标签,例如2米。 Each display element 18 has an RF transceiver 56, it is possible to further facilitate the detection of all the RFID tags within a predetermined range, for example 2 meters. RFID标签位于每个库存条目上,允许显示元件18检测到来自库存条目的信号,后者位于一系列元件中。 RFID tags located on each stock entry, allowing the display element 18 detects a signal from the entry of the stock, which is located a series of elements. 位于显示元件18中的微控制器52能够比较检测到的RFID标签306,它可传送信息标识符,允许所附的产品确定,将信息显示在显示元件上。 Product RFID tag located in the display element 18 in the microcontroller 52 is capable of comparing the detected 306, which may transmit information identifier, allowing the appended determining, displaying information on a display device. 因此,设置范围内的存货水平的测量和存货类型可轻松获得。 Thus, the level of inventory in the specified range and the measurement type can easily be obtained inventory. 当显示元件18 处于下一个唤醒状态,它向计算机27传递回货架上的实际产品数目,并且计算机27能够比较货架剩余数目与系统规则36确定是否需要补充。 When a display element 18 is in the awake state, it is passed back to the actual number of products on the shelf 27 to the computer, and the computer 27 can compare the number of remaining shelf system 36 determines whether the rules need to be supplemented. 如果微控制器52确定存货水平,那么将向计算机27发送信息,以提升存货水平。 If the microcontroller 52 determines inventory levels, then the computer 27 will send information to improve inventory levels.

[0257] 此外,为了节约电量,SYNC脉冲包括一个唤醒传感器和扫描命令。 [0257] Further, in order to save power, the SYNC pulse and a scanning sensor comprising a wake-up command. 唤醒传感器和扫描命令为RFID收发器56供能,检测预定范围内的具有RFID标签306的所有产品,通过RFID的识别信号确定该范围内的差篇,向计算机27传输信息,并使RF收发器56回到睡眠模式。 Wake-up sensor and scanning command RFID transceiver 56 energizing all products having the RFID tag 306 is detected within a predetermined range, determining a difference within the range published by RFID identification signal, the transmission of information to a computer 27, and an RF transceiver 56 back to sleep mode. 为了进一步节约电能,唤醒传感器和扫描命令的定时是以时间为依据的。 To further save power, wake-up sensors and the timing of the scanning commands is time-based. 例如,在购物的最高峰时间内,唤醒传感器和扫描命令将有规则的启动,例如每10分钟,在较低的顾客量时期,甚至是数小时内,库存有可能维持在近似恒定水平。 For example, in the peak shopping hours, wake-up sensor and scan command a regular starting, for example, every 10 minutes, at a lower amount of time customers, or even within a few hours, it is possible to maintain the stock at approximately constant level.

[0258] 该领域技术人员可能会想到传感器的使用并不仅仅局限在RFID标签和RF收发器56。 [0258] skilled in the art might think of using the sensor is not confined to the RFID tag and the RF transceiver 56. RFID标签306的使用允许轻松整合现有结构,其中RF收发器56已然存在于该显示元件18中。 RFID tag 306 is used to allow easy integration of the existing structure, wherein the RF transceiver 56 is already present in the display element 18. 重量传感器用于测量货架上库存的当前重量,库存剩余总数与所检测到的重量成正比。 A current sensor for measuring the weight of the weight of the stock on the shelf, the remaining stock is directly proportional to the total number of the detected weight. 光线传感器用于检测货架上库存的高度,这将指出库存水平。 Light sensor for detecting the height of the stock on the shelves, which will indicate the level of inventory. 在优先实施例中,该传感器能够提供库存类型相关信息。 In the preferred embodiment, the sensor can provide information about inventory type. 这些信息与库存类型有关,允许在单独的唤醒传感器和扫描命令下,监测多条目的库存水平 The information related to the type of stock, allowing the individual sensors and the scanning wakeup command, a multiple-entry monitoring inventory levels

[0259] 除了在零售部门,显示系统还可用于饭店,例如显示订单相关信息,例如手动传输的无线显示模块,顾客能够使用具有序号的显示模块及其购买的条码,包括顾客选择的表格以告知服务于相应订单的位置。 [0259] In addition to the retail sector, the system also displays the bar for the hotel, for example, display order information, such as a manual transmission in a wireless display module, the display module can be used with the customer number and purchase, including a table selected by the customer to inform services in the appropriate order of position.

[0261] 在医疗环境下显示系统的使用,例如告知储备的一个或多个医院床位;现任的医疗细节;位置认识和规定的显示位置;即将进行手术的时间、位置和医生姓名;用药频率和服用禁药水平;登记号(例如,婴儿吊床)、手术设备和药物储备。 [0261] use in the medical environment display system, such as a reserve inform or more hospital beds; current medical details; recognize and display position specified; upcoming surgery time, location, and the doctor's name; and frequency of administration doping level; registration number (e.g., hammocks baby), surgical equipment and drug reserves.

[0262] 军事环境下显示系统的使用,例如向本机命令发送命令和控制信息,本机命令最好能够向200m半径范围内的人员发送(编码的)命令、地图。 [0262] command to the system, such as sending command and control information to command the machine, the machine is preferably able to send commands to a person within a radius of 200m (encoded) under military environment map.

[0263] 仓库中的显示系统的使用,例如在仓库中的条目入库期间显示其位置、库存水平、 本地指令(例如,命令、地址等)。 Indicating its location, stock level, local instructions (e.g., command, address, etc.) during the [0263] display system used in a warehouse, for example, the entry in the storage warehouse.

[0264] 最后,值得注意的是,现有系统为各个ESL元件(显示模块18)使用多个时隙,从而大大减少能力损耗。 [0264] Finally, it is worth noting that the existing system elements for each ESL (display module 18) using a plurality of time slots, thus greatly reducing the capacity loss. 例如,见图4使用了4时隙。 For example, Figure 4 uses 4 slots.

[0265] RF协议通过使用SYNC数据包和时间分隔多路技术(时隙)的结合来优化现有的消耗和频带宽度。 [0265] RF protocol by using the SYNC packet and time division multiplexing (time slot) to optimize the combination of existing and bandwidth consumption. 通讯器在每个时隙(I. Is)传送多个SYNC数据包。 Communication transmits a plurality of packets in each slot SYNC (I. Is). 根据RF地址,将每个显示器分配给一个时隙。 The RF address, assigning a time slot to each display. 该方案允许100%的可利用频带宽度,但每个显示器只能唤醒其分配的时隙。 This scheme allows 100% of the available bandwidth, but each display can only wake up its assigned time slot. 时隙数量是2的倍数。 2 is a multiple number of slots. 增加时隙数目可降低显示器的能量消耗,从而得到更长的回应时间。 Increasing the number of slots may reduce the energy consumption of the display, to thereby obtain a longer response time.

[0266] 在每个时隙开始时,发送包含有奇数个SYNC数据包的区块。 [0266] at the beginning of each time slot, transmits SYNC blocks with an odd number of packets. 每个SYNC数据包含有来自中部SYNC数据包补偿(例如,t = -2, t = -1,t = 0, t = 1,t = 2等),允许显示器与中部SYNC数据包(t = 0)重新同步化,通过在收到的第一个SYNC数据包的基础上调整时钟。 Each SYNC from a central data with compensation SYNC packet (e.g., t = -2, t = -1, t = 0, t = 1, t = 2, etc.), allowing the display to the middle SYNC packet (t = 0 ) re-synchronization, on the basis of the first clock by adjusting a sYNC packet received on. 这使得该协议依靠较少的准确性和成本相对较低的晶体振荡器而具有时刻漂移的弹性。 This makes the protocol relies on a relatively low cost and low accuracy crystal oscillator drift time has elasticity. 保持显示器与通讯器的同步通常需要一个低容忍力32KHz时钟晶体,但也具有微控制器的内部RC振荡器的功能,进一步节约成本。 Holding display and synchronization of the communication device typically requires a low tolerance crystal force 32KHz clock, but also having an internal RC oscillator functions of the microcontroller, further cost savings.

[0267] 发明者发现,如果每个显示模块大约每8秒被唤醒一次的话会非常节能。 [0267] The inventors found that, if each display module approximately every eight seconds, then wakes up a very energy-efficient. 然而,在一个特定的环境中,特定的模块可能会因为热闹的超市中的RF干扰而无法收到一些SYNC 脉冲的同步化信号。 However, in a particular environment, a particular module may be due to RF interference busy supermarket and can not receive some of the synchronization signal SYNC pulse. 使用我们现在的系统,在每个SYNC脉冲中传送多个SYNC数据包。 We now use the system, a plurality of transmitting data packets in each SYNC SYNC pulse.

[0268] 如果使用5个SYNC数据包,在失去与通讯器的同步化之前,显示器的时间可趋于3 个SYNC数据包(t = 0, t = 1,t = 2),例如在每个唤醒时期之间,时钟可漂移至11. 25ms。 [0268] Using 5 SYNC packets, before they lose their synchronization with the communicator, the display time may tend to three SYNC packet (t = 0, t = 1, t = 2), for example, in each between the wakeup period, the clock can drift to 11. 25ms. 每个组件具有一个晶体振荡器,其精确性达百万分之20 :这意味着该振荡器可漂移至每个唤醒时期间的0. 16ms,在指导重新同步化扫描之前,使显示器放松最大70SYNC脉冲,或616 秒(70*唤醒时期)。 Each component has a crystal oscillator accuracy of 20 parts per million: This means that the oscillator may drift to the period when the wake-up each 0. 16ms, before guiding resynchronization scan, the display maximum relaxation 70SYNC pulse, or 616 seconds (70 * wake-up period).

[0269] 如果发送单一的SYNC数据包,那么该漂移需要精确到3ms内。 [0269] If the transmission of a single SYNC packet, then the drift is accurate to within 3ms. 因此,液态的晶体模块可能在18个SYNC脉冲之后需要一个再同步化扫描,仅有158秒。 Thus, the liquid crystal module 18, possibly after a SYNC pulse needs resynchronization scan, only 158 seconds.

[0270] 如果该组件在某个时段(例如50至100个时隙)没有收到SYNC脉冲,那么显示模块必须进行重新扫描来寻找SYNC脉冲。 [0270] If the component does not receive SYNC pulse in a certain period (e.g. 50 to 100 slots), the display module is to be re-scanned to find the SYNC pulse. 除了在高功耗下的3ms进发,该过程需要一个高功耗下Is的完整时隙。 In addition to 3ms embarked at a higher power, the process requires complete timeslots Is the next high power consumption. 也就是说,如果因RF干扰损失了SYNC脉冲,那么需要消耗333多倍的能量。 That is, if lost due to RF interference SYNC pulse, you need to consume 333 times more energy. 这种干扰可能来自周围物体的电干扰,改变显示模块的局部环境(例如,金属物体、电车和超市营业时期的其他局部变化)。 This interference may come from the local environment around the object to electrical interference, change the display module (e.g., metal objects, trams and other local supermarket sales period change). 为了消解这一问题,发送一系列的SYNC脉冲, 包括先前和随后的预期平均时间脉冲。 To this digestion problem, sending a series of SYNC pulse, including previous and subsequent expected average time pulse. 这大大提高了元件接收SYNC脉冲的精确度,并保证电力保持在最小水平。 This greatly improves the accuracy of the SYNC pulse receiving element, and to ensure that the power level is maintained at a minimum.

[0271] 零售环境有数千个液态晶体模块,与单独的通讯器相连。 [0271] There are thousands of retail environment liquid crystal module, connected with the separate communication device. 不仅成本低、具超低电压,而且是可靠的。 Not only low cost, with ultra-low voltage, and is reliable. 本发明一方面使用多种SYNC脉冲数据包,有助于确保超低电力消耗,同时确保较少发送再次同步化扫描,并且该系统是可靠地。 In one aspect of the present invention using a variety of SYNC pulse packet, help ensure low power consumption, while ensuring that fewer scans synchronized retransmission, and the system is reliable.

[0272] 申请人还使用两项附加过程,优化了显示模块18与通讯器12同步化过程: [0272] Applicants also used two additional process to optimize the synchronization of the display module 12 and communication device 18 process:

[0273] 多点传送(再同步): [0273] Multicast (resynchronization):

[0274] 在设置为"再同步"命令字节时,"唤醒"数据包的连续流在配置通道(不属于LBT(发前听)规则)上传送。 [0274] When set to "resynchronize" the command byte, "wake up" a continuous stream of data packets arranged in the channel (not LBT (listen before the onset of) rules) on the conveyor. 这大约传送15秒(例如,长于所有时隙的总时间),以确保可在此时期唤醒所有的显示器。 This transfer is about 15 seconds (e.g., longer than the total time of all timeslots) to ensure that all of the displays can wake up during this period. "再同步"命令通知显示模块18能够在等候15秒后是同再同步,允许通讯器12定时启动再次发送SYNC数据包。 "Re-synchronization" command instructs the display module 18 can be the same resynchronization after waiting 15 seconds, allowing the timing to start transmitting communicator 12 SYNC packet again. 只有可听从配置通道的显示模块18将接受该命令。 You can only listen to the channel display module 18 configured to accept the command. 也就是说,可使用一个默认通道,其中任何显示模块18不再与通讯器12 进行再同步,等待"再同步"命令,随之而来的是显示模块18开始听从适当的同步化信号通道,用于其适当的时隙。 That is, use a default channel, the display module 18 is no longer any re-synchronization and communication unit 12, waits for "re-synchronization" command, followed by the display module 18 begins to listen proper synchronization channel signal, for its appropriate time slot.

[0275] 同步风暴: [0275] Synchronization storm:

[0276] 在正常的操作中,通讯器12在时隙起点发送一系列同步数据包(通常是5个)。 [0276] In normal operation, the communication unit 12 sends a series of synchronization packets (typically 5) at a slot starting point. 在"同步风暴"模式下,通讯器12发送连续的同步数据包(在标准的通讯通道,服从LBT规则),允许不同步的显示模块18重新同步,无需必须进行全部重新扫描。 In the "synchronous storm" mode, the communicator 12 sends successive synchronization packets (in the standard communication channel, subject to the rules LBT), allowing the display module 18 are not synchronized resynchronization without having to re-scan for all. 同步风暴持续多数,最好是3个完整的时隙,因为一些显示模块18可能不同步程度较高,抵消同步化数据包以提供足够的信息使他们再核算正确的同步化时间。 Most synchronous storm continued, preferably three entire time slot may be higher because some display module 18 not synchronized extent, offset the synchronization data packets to provide enough information to enable them to re-synchronize the correct accounting period. 该同步通讯风暴在每个显示模块18 分组的每个时隙内最好包括一系列同步化数据包。 The synchronous communication storm preferably includes a series of synchronization packets in each time slot of each display module 18 packets. 最好以相似于标准的5个同步信号(例如,标记分隔率)的方式联系整个时隙的始末。 Preferably similar to the standard 5 sync signal (e.g., the partition labeled rate) manner to contact the whole story of the entire slot. 每个信号最好根据时隙(显示模块18分组)包括一个标签,一个相对位置或时隙内的次数,从而确保显示模块转换至不同时隙的唤醒时刻,或至一个时隙内的不同次数。 Preferably each signal in accordance with a relative position of the number of time slots within a slot (packet display module 18) comprises a label or to ensure that the display module is switched to a different wake-up time slots, or to a different number of times within a slot . 而且,该"风暴"最好发送至3个完整的连续时隙。 Further, the "storm" is preferably transmitted to the complete three consecutive time slots.
